Not sure if anyone will share any info on it or not, but whats it do ? I see them a lot nowadays.
I would think its so you could run a softer spring to help get the Car to steer, but then not fall off a cliff if you get out of the Gas real quick but i never ran one to know.
It's about having two different rates and a reliable stopping point. Reasons can include wanting a soft spring to aid weight transfer upon acceleration, soft rate on initial turn-in as you suggested, or probably quite a few other uses. It can actually be easier to tune entry with one, IMO, especially where you slow a lot before entering the corner.Quote:

I guess i need to get one on and start tinkering with it LOL.
I'd say the weight transfer deal would not be a modern use. Back in the leaf and early 4 bar days, guys would run dual rate across the front to have a light rebound rate for maximum weight transfer. You could drag race like nobodies business. Entry was another story...Quote:

at lawrenceburg it would coil bind the RF because of the waves, woop sections in the track.
It is still the same as the left rear, using a soft spring maintains more weight on the tire for the same amount of travel.Quote:

For a given travel, softer spring maintains more load.
For a given unload, softer spring travels farther.
Raising the center of gravity is generally synonomous with weight transfer.
So your saying in simple terms that the LF Spring can retain some weight longer with the lighter spring, makes since.
A 275 and 225, thats crazy.
after watchinq a few usmts races this year i think they might have the bump stops on the LF to act as litteral bump stops. a lot of them dropping pretty hard onto the LF on entry
